How do I find the factors or divisors of the number 657,120,012?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the factors of larger numbers. To find the factors of the number 657,120,012, it is easiest to start from the outside in. Here's what we mean:

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table.

1 657,120,012

Next, we take the number 657,120,012 and divide it by 2.

In this case, 657,120,012 ÷ 2 = 328,560,006

If the quotient is a whole number, then 2 and 328,560,006 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 328,560,006 657,120,012

Now, we try dividing 657,120,012 by 3.

657,120,012 ÷ 3 = 219,040,004

If the quotient is a whole number, then 3 and 219,040,004 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 3 219,040,004 328,560,006 657,120,012

Let's try dividing by 4.

657,120,012 ÷ 4 = 164,280,003

If the quotient is a whole number, then 4 and 164,280,003 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 3 4 164,280,003 219,040,004 328,560,006 657,120,012

We keep dividing by the next largest number, in this case the number 5. If the quotient of 657,120,012 ÷ 5 is a whole number, then 5 and your quotient are factors of the number.


Keep dividing by the next highest number until you cannot divide anymore.


What you will end up with is this table:

123461273146219292438876750,1371,500,2742,250,4113,000,5484,500,8229,001,64454,760,001109,520,002164,280,003219,040,004328,560,006657,120,012

All of the numbers in the table above can be evenly divided into the number 657,120,012.
